I'm sorry for the off topic. What is the 1x1 method?
Back to the topic. I'd get the headstuds and a new gasket. Rather spend a few hundred bucks then a couple grand to rebuild the motor.
If you have another daily driver and the Evo is just a toy to you, go head and run 30psi and see what happends....lol. Then come back and tell us if everything is good.

Your kind of gambling either way. If you pick the 1x1 method your at risk for possible failure and if you just throw 30psi at the stock bolts you could have possible failure. There is a poll somewhere on here that showed the success and failures of the 1x1 method. If i recall alot of people had some sort of issue down the road with the 1x1 method. I am personnaly going to run a red on 25-27 psi with the stock bolts and if i have issues with the head lifting i am going to pull the head and replace the bolts with studs. I was quoted 600 in labor to pull the head and install the arp's. $100 for arp's + (50-100) for headgasket + (100-150) for timing belt + (600-800) Labor and any other miscelanious parts you may need = 850-1150 all together which is a pretty decent amount of money. If FastAzzEvo is running an 850R with 25-30 psi that should be a perfect example of what the stock bolts can handle. There are plenty of people running the stock bolts and untill i see some information on them lifting their heads my opinions will remain the same. In my opinion if you are going to install the studs do it right the first time. I would personally feel that somthing would go wrong down the line if i did the 1x1 method, but this is just my opinion. Good luck with your choice.

Here we go again. This has been beat to death, there are many thread on this subject.
FWIW, I went the 1X1 method nine months ago, running 28psi E85, and no leaks at all. If done correctly, it should never leak. Do a search and you'll see some big name shops that do this all the time, with no issues. The key is a shop that knows what there doing.

Alright, So if you don't swap them out 1 by 1, then how exactly. Take them all out at once and then install the new ones in 1 by 1....going in a certain order, I'll figure out the order later.
You will need to pull the head from the car, replace the HG, then reinstall following proper order and torque specs

As posted many times before I have a red and have stock head studs with no issues. I run meth and 30psi daily. My tuner has stock studs and runs 30psi with a 35R. You will be ok. I would only put them in if the head if already lifted or with a built engine when its assembled.
I have a dollar for anyone who can prove they lifted a head with 30psi or under.
